Float Calibration (For Header Without Sensors)

The pressure sensor is calibrated for the header installed on the combine in the float system calibration procedure. The float calibration procedure must be performed when a header is initially hooked up if the ground pressure (float) mode of operation will be used.

Prepare Header For Calibration:

Turn the key switch to the run position.

Hook up header to the combine and ensure header harness is connected to combine harness. Move the machine onto a level surface.

While in this mode, the feeder house may be moved in open loop control.

With the header lift switch on the multifunction lever, lower the header until the cutterbar is about 100 mm (3.94 in.) above ground level (the header must not touch the ground).

Press the calibration switch. 103 and EOC will appear on the tachometer.

OUO6075,0000355 -19-08JAN01-8/9

Press the enter switch to store the float calibration pressure in the header controller. 103 and FCAL will appear on the tachometer.

Press the back arrow switch twice to return to normal operation.
